Ukraine has used a combination of American and Soviet-era missiles to take down nine Russian fighter-bombers and one A-50 radar plane in a short span of time, while Russia struggles to replace its losses and detect Ukrainian launches.
In his daily address to the nation, the President of Ukraine thanked the West for providing air defense systems and talked about Ukraine's long-range weapons.
